DEPARTMENT OF HOMELAND SECURITY

Coast Guard

[Docket No. USCG-[USCG-2021-0042]]


Revisions to Maritime Security Directive 104-6; Guidelines for 
U.S. Vessels Operating in High Risk Waters

AGENCY: Coast Guard, DHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard announces the availability of Revision 8 to 
Maritime Security (MARSEC) Directive 104-6, which provides guidelines 
for U.S. vessels operating in high-risk waters (HRW) where acts of 
terrorism, piracy, and armed robbery against ships are prevalent. The 
directive contains security-sensitive information and, therefore, 
cannot be made available to the general public. U.S. vessel owners and 
operators who have needed to take action under previous versions of 
MARSEC Directive 104-6 should immediately contact their local Coast 
Guard Captain of the Port or District Commander for a copy of Revision 
8. This revision contains important updates to HRW locations and 
organizational responsibilities regarding addressing security risks in 
those waters.

DATES: MARSEC Directive 104-6 (Revision 8) has been available since 
August 11, 2021. MARSEC Directive 104-6 (Revision 7) is no longer valid 
after that date.

FOR FURTHER INFORMATION CONTACT: For information about this document 
call or email LCDR Michael Metz; U.S. Coast Guard, Office of Commercial 
Vessel Compliance; telephone 202-372-1236, email [email protected].

SUPPLEMENTARY INFORMATION: Maritime Security (MARSEC) Directive 104-6 
Revision 8 replaces Revision 7, previously signed on March 4, 2014. The 
new directive provides direction to U.S. flagged vessels operating in 
High Risk Waters (HRW) where acts of terrorism, piracy, and armed 
robbery against ships are prevalent. This revision reflects a change in 
organizational responsibilities and updates the list of regions 
identified as HRW.
    U.S. vessel owners and operators who have needed to take action 
under previous versions of MARSEC Directive 104-6 should immediately 
contact their local Coast Guard Captain of the Port or District 
Commander for a copy of Revision 8, which contains important updates to 
the locations of HRW and to the guidelines for addressing security 
risks in those waters. The Coast Guard advises owners and operators 
that, under Revision 8, they may need to take specific actions in 
accordance with MARSEC Directive 104-6 before their vessel enters HRW.
    This notice is issued under authority of 33 CFR 101.405(a)(2) and 5 
U.S.C. 552(a).

    Dated: August 23, 2021.
W.R. Arguin,
Captain, U.S. Coast Guard, Director of Inspections and Compliance.
